Solar trickle chargers
Has anyone tried running a solar panel to supplement the vehicle charging system, and were there any gains worth the trouble? It seems any load removed from the engine would be a good thing, but I'm thinking the 4 watts (optimistic) that most car trickle charge panels put out might be a drop in the ocean. I was thinking specifically of the VW panels that can be had for free if you know where to look..
